Key finding
HbA1c was reduced by -0.40% [95% CI -0.61 to -0.18].
This study compared aerobic and resistance exercise training in older adults with Type 2 diabetes who were dieting. Both interventions showed improvements in HbA1c levels.

Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
This study compared aerobic and resistance exercise training in older adults with Type 2 diabetes who were dieting. Both interventions showed improvements in HbA1c levels.
These findings are significant as they demonstrate that both aerobic and resistance exercises can be effective strategies for managing blood sugar levels in older adults with Type 2 diabetes. This can aid healthcare providers in designing comprehensive treatment plans that include physical activity as a key component.
Limited sample size may affect generalizability. No significant changes in muscle strength were observed in one group. The study did not measure long-term effects beyond the intervention period.

HbA1c was reduced by -0.40% (p=0.001) in the aerobic training group.
HbA1c was reduced by -0.35% (p=0.001) in the resistance training group.
Insulin sensitivity increased significantly in both intervention groups.
